45、uirements for metallic plug valves as follows. Steel, nickel base, and other alloy plug valves with flanged or butt-welding ends and ductile iron plug valves with flanged ends in sizes 15 DN 600 (1/2 NPS 24). Threaded or socket-welding ends for sizes 15 DN 50 (1/2 NPS 2). Valve bodies conforming to
46、ASME B16.34 may have one flange and one butt-welding end, or one threaded and one socket-welding end. Lubricated and nonlubricated valves that have two-way coaxial ports. Three-way and four-way plug valves do not fall under the scope of this standard. Tandem plug valves which have two independent op
47、erating plugs in a single body.This standard includes requirements for valves fitted with internal body, plug, and port linings or applied hard facings on the body, body ports, plug, and plug port. The extent of linings and the facing materials of which they are made are not covered in this standard
48、.This standard also provides additional requirements for plug valves that are in full conformance to the requirements of ASME B16.34 for Standard Class 150 through 2500. Ductile iron valves, Class 150 and 300, shall follow the additional requirements of ASME B16.42 for pressure-temperature ratings,
49、wall thickness, flange dimensions, and material grade. Plug valves covered in this standard belong to one of four general design groups that in many cases have different face-to-face and end-to-end dimensions. Some types of plug valves are not made to all patterns. The four groups of valve design are described below. Short pattern design found only in Class 150 and 300 where flanged plug valves match the face-to-face dimensions of steel-flanged gate valves in sizes 40 DN 300 (1 1/2 NPS 12). Regular pattern design with a plug port area that is greater than
